Structural and electrochemical investigation of lithium ions insertion processes in polyanionic compounds of lithium and transition metals

The paper considers approaches to the synthesis as well as the structural and electrochemical properties of lithium and transition metals polyanionic compounds as promising cathode materials for lithium-ion battery. The characteristics of lithium and transition metals sulfates are considered, among which iron-lithium sulfate and a composite electrode material Li2Fe(SO4)2/C based on it was selected for further detailed study. The relationships...
